Periodic Fourier interpolation gave a mean squared error ratio of 0.0066 for alternating samples in 100 cortical regions from 20 filtered ds006192 movie runs with odd input lengths
We tested reconstruction of alternating samples in 100 cortical regions from 20 stored movie fMRI runs in OpenNeuro ds006192 version 1.0.0. Ten people contributed two movies each. A fixed periodic Fourier rule used odd input lengths. The mean squared error ratio was 0.006634. Its person bootstrap 95% interval was 0.005174 to 0.008429. Circular linear interpolation gave a ratio of 0.048050. A finite-array proof links each directional error exactly to twice the full-record high-mode energy. This identity needs no ideal filter assumption. An independent real-matrix calculation checked predictions, scores, and correlation bounds. All 215 source files matched the fixed release and their content hashes. A full rerun from new downloads reproduced all 12 numerical result files byte for byte. The package contains source data, code, every primary prediction, controls, proof, and instructions. The result measures reconstruction within complete-run processed signals. It does not test a new run or identify the neural source of the residual.

This study used the exact ten-person source subset from this publication. Its alternating connectivity result and strict frequency proof motivated the new sample predictions and finite residual identity.
